IM PROVEM ENT lN PRUNI NG-SH EARS.

Specification forming part of Letters Patent No. 218,233, dated August5, 1879; application filed May 24, 1879.

To all whom it may concern:

Be it known that I, GEORGE J. GLINE, of Goshen, in the county oflllkhart and State of Indiana, have invented a new and valuableImprovement in Pruning-Shears; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a side view of myimproved shears. Fig. 2 isa detail view of the hook-head and upperknife, and Fig. 3 is an edge view of the shears complete.

This invention has relation to pruningshears; and it consists in theconstruction and novel arrangement of the hooked slide-head, the upperblade pivoted at one end to the end of the hook and at the other to theend of the vertically-working slide-rod, the lower blade pivoted at itsmiddle portion to the body of the hook, and having a slide end, whichworks in a notch of the operating-rod, all as hereinafter fully shownand described.

In the accompanying drawings, the letter A designates the slide-head,the upper end of which is in hook form, as shown, the hook portion beingdepressed a little down to the shoulder a, to afford room for theoperation of the upper knife, B. This knife or blade is pivoted at itsforward end to the end of the hook, as shown at b, its rear end beingpivoted to the upper end of the vertically-working operating-rod C. Tothis rod the lower end of the slide-head A is connected by means of aneye, 0, through which the rod passes.

The lower blade or knife, D, is pivoted at its middle portion or body tothe shank of the hook, just below the shoulder a, and is provided with aguide arm or spur, d, which pro jects upward, and engages the side ofthe upper knife as it descends, thereby keeping the two knives or bladesin proper relation under strain.

The rear end of the lower blade is made in the form of a slide-arm, t,which works in a notch or seat, 6, in the operating-rod below the pointat which the rear end of the upper blade is pivoted. Therefore it doesnot interfere with the vertical working of the rod. The stroke of thelower blade is in a direct line between the pivotal point of the upperblade and the eye 6. At the same time this eye or slide seat 0 forms astop, preventing the slidehead from falling too low.

The blades are opened by the gravitation 0f the slide-head, the upperblade rising in rear of its pivot to the hook and the lower bladefalling, thereby, with comparatively slight motion of the slide-head,affording a large space.

The cutting is effected by drawing down the operating-rod, which quicklydepresses the upper knife and raises the lower one, so that they arebrought into engagement.

The shoulder a serves to engage the rear portion of the upper knife whenthe cut is fully made, forming a stop, under the operation of which theblade cannot be strained, because it is between the pivotal points ofsaid blade.

These shears are simple in construction, readily operated, and verystrong, being, on account of the end pivoting of the upper blade and itsbacking against the hook, but little liable to a twisting strain.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The pruning-shears consisting of the hooked slide-head A, the upperblade, B, pivoted at one end to the end of the hook and at the other endto the end of the operating-rod,which moves in slide eye 0 upon theshank of the slidehead, and the lower blade, I), pivoted at its middleportion to the body of the hook, and having a slide end, t, which worksin a notch or seat of the operating-rod, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

GEORGE J. OLINE.
